# Changelog for `proto-lens`


## v0.7.1.2
- Support GHC 9.4

## v0.7.1.1
- Relax upper bounds for ghc-9.2

## v0.7.1.0
- Support GHC 9.0.
- Fixed parsing of UTF8 chars in text format proto string literals.
- Support all valid text format boolean field values
- Remove redundant (.&. 127) from putVarInt (#396)

## v0.7.0.0
- Support GHC 8.10.
- Add a method to `Data.ProtoLens.Message` for getting the `DescriptorProto`
  of a given message.  For a simpler API, see `Data.ProtoLens.Descriptor`
  from `proto-lens-protobuf-types`.
- Bump ghc-source-gen to version 0.4.0.0.
- Bump upper bound to allow base-4.14.
- Bump upper bound to allow ghc-prim-0.6.

## v0.6.0.0

### Breaking Changes
- Bump lower bounds to base-4.10 (ghc-8.2).
- Move `Proto.Google.Protobuf.Descriptor` and
  `Proto.Google.Protobuf.Compiler.Plugin` to the `proto-lens-protobuf-types`
  package.

### Backwards-Compatible Changes
- Bump upper bound to allow profunctors-5.5.
- Support dependencies on base-4.13 (ghc-8.8) and lens-family-2.0.

## v0.5.1.0
- Add `decodeMessageDelimitedH` to decode delimited messages from a file handle
  (#61).

## v0.5.0.1
- Bump the upper bound on `profunctors` to allow 5.4.
- Bump the upper bound on `primitive` to allow 0.7.
- Allow text format protobuf strings to contain unescaped quote characters
  different from the delimiters (#320).

### Breaking Changes
- Merge the `lens-labels` library into `proto-lens`:
    - `Lens.Labels` => `Data.ProtoLens.Fields`
    - `Lens.Labels.Unwrapped` => `Data.ProtoLens.Labels`
    - `Lens.Labels.Prism` => `Data.ProtoLens.Prism`
- Simplify the API of `Data.ProtoLens.Encoding.Wire`, using a plain ADT
  rather than a GADT to represent unknown field values.
- If fields have the wrong wire type, store them in `unknownFields` rather
  than failing the parse. (#125)

### Backwards-Compatible Changes
- Merge proto-lens-combinators into the proto-lens library.
- Use generated Haskell code to encode/decode proto messages more quickly.
  In particular:
  - Add the methods `parseMessage` and `buildMessage` to `Data.ProtoLens.Message`
  - Expose an opaque `Parser` monad, which is used by the generated
    code.
  - Expose the module `Data.ProtoLens.Encoding.Bytes`, which is used
    by the generated code.
  - Various other, related performance optimizations.
- Add functionality for storing unknown fields as `Vector`s.  (See the
  changelog of `proto-lens-protoc` for more details.)  Exposes the
  `Growing` type for mutable vectors of growing capacity.
- Export the new function `parseMessageDelimited`. (#61)

## v0.4.0.1
- Bump the dependencies on `base` and `containers` to `0.4.0.1`.

## v0.4.0.0
- Don't use `data-default` for default proto values (#194).
- Update the proto descriptors to protobuf-3.6.1.
- Use simplified lens-labels instances. (#208)

## v0.3.1.1
- Bump the lower bound on `base` to indicate we require `ghc>=8.0`.

## v0.3.1.0
- Improve references to types/fields in decoding error messages (#187).
- Bump the dependency on `base` for `ghc-8.4.2`.
- Make `Registry` an instance of `Semigroup`.

## v0.3.0.0
- Remove support for `ghc-7.10`. (#136)
- Use a `.cabal` file that's auto-generated from `hpack`. (#138)
- Add buildMessageDelimited: size-delimited streams of Messages (#102)
- Add support for parsing `Any` messages in google protobuf text format (#124)
- Use the Tag newtype consistently. (#127)
- Add support for tracking unknown fields. (#129)
- Improve an error message. (#132)
- Bundle enum pattern synonyms with their type. (#136)
- Implement proto3-style "open" enums. (#137)
- Consolidate `proto-lens-descriptors` into `proto-lens`. (#140)
- Split the `Message` class into separate methods. (#139)
- Improve an error message when decoding Anys. (#146)
- Refactor the `FieldDescriptorType. (#147)
- Improve text format error messages. (#148)
- Add module `Data.ProtoLens.Service.Types`. (#154)
- Add Haddock comments to fields. (#172)

## v0.2.2.0
- Bump the dependency on `base` to support `ghc-8.2.1`.

## v0.2.1.0
- Include `base`'s modules in the reexport list.
- Use custom-setup in packages that depend on `proto-lens-protoc`.
- Allow `.proto` files to import between Haskell packages.
- Add the `proto-lens-protobuf-types` package.

## v0.2.0.1
- Make the libraries '-Wall -Werror'-clean for the latest
  version of GHC.

## v0.2.0.0
- Support OverloadedLabels with the new `lens-labels` package.
- Fix codegen for field names that are already camel-cased.
- Increase version bounds to work with Stackage lts-8.

## v0.1.0.5
- Fix the handling of packed repeated fields (#38)
- Improve space usage and time of decoding (#63)
- Print fields ordered by tag number (#40)

## v0.1.0.4
- Relaxed dependency constraints on data-default-class for
new stackage LTS.

## v0.1.0.3
- In printing and parsing protocol buffers use/interpret escape
sequences in a way compatible with the Protocol Buffer
distribution's C/C++ escaping style, closing Issues #44 and
#45. This makes the text output incompatible with previous
versions; earlier versions will misinterpret text written by this
version and this version will misinterpret text written by
previous versions.
- Support reading text protocol buffers with single quote characters
(') for string delimiters, closing Issue #20.

## v0.1.0.2
- Expose more of protoc-gen-haskell to plugins.
- Support enum aliases.
- TextFormat prints enum names instead of numbers.

## v0.1.0.1
- Support ghc-8.
- Handle .proto files without a "package" declaration (#11).

## v0.1.0.0
- Initial version.
